Stuck on side of the road!!!!

[7.3joker]

Was runnin down the road and engine just died. Took the air filter out and it cranked back up and drove a couple hundred feet and died again. Couldn't get it to crank after that. Put a new fuel pump on it and blew air from where the pump hooks up back into the fuel tank and got fuel coming out of the line again. Fuel bowl fills up quick when you turn the key on. Runs on ether but runs rough. unplugged icp sensor no change. ANY help would be much obliged!

#1 STOP the Either! You're gonna hurt something because your engine uses Glow Plugs... (use Brake Clean instead)

Second, you need to include the yr/mdl/mods because different versions have different diagnosis procedures.

What's the status of your CPS?

If your truck is a 2001 or below, without a trans temp gauge in the cluster, you should see the tach move up slightly as your are cranking.

Is the truck "chipped"? (disconnect it as a test)

Do you get a WTS light, when you first roll-on the key, now? Has it been running OK up 'till now? No SES light?

where are you???

Jacksonville. It's a 99 f-250 7.3L bone stock. I do get a wts light i had that problem a couple weeks ago and replaced a fuse and it started working. Whats a cps? Only a abs light is on. I cant remember if the tach was moving when i cranked on it or not. I'm 3 hours away now but do have someone going to fetch it

You had this problem before and a fuse fixed it? What fuse was that?

The CPS is the Crank Position Sensor located at the harmonic balancer. If you don't see tach movement it means it's not sending a signal to the computer.

There are actually TWO '99s, and early & late '99 depending on the mfg date. Look on the door sticker to tell 12-98 and down is "early")

is there any way to test the cps? it was a 10 amp fuse inside the truck in the dash. I found a thread on here about it

[NoRalPh]

Again, the best test is the tach But when I asked about the "status" it's because the original one was Very prone to failure and Ford had a recall to replace them all. I have to assume, in all this time, chances are yours has been replaced already (the Org one was Black, the replacement gray, just look at it) BUT they still fail and I think everybody should be carrying a spare anyway...

Look and see if you can find the fuse # (and weather yours is a early or late), it might help to figure-out if it has anything to do with the current situation.

i think its an early model. My dad will be back down there in a couple hours to get it i'll have him check that for me. The cps has ben replaced previously but the truck does have 333k on it! I wanna say it was either #14/16 fuse

This is terrible advice. While starting fluid is dangerous in applications with glow plugs, brake cleaner is highly toxic when burnt. Just a wisp of the smoke produce can kill you.
